My memory is a bit hazy as it was over 10 years ago, but I believe this top was purchased from a gyaru brand. It has been worn a few times, washed, and stored in a dark place. It's a women's M size, but the design is slim, so it might also fit children around 140-150cm. How about it for the Heisei boom? ♡ Measurements (flat lay): Width: 36cm Length (underarm to hem): 37cm Sleeve length: 13.5cm Please feel free to ask if you have any questions ☺︎ Please purchase only if you understand that this is a used item.
